UOP 883 – Purity of UOP No. 5 Inhibitor by Capillary Column GC
This method is for determining the purity of UOP No. 5 inhibitor (NN‘-di-sec-butyl-p-phenylenediamine). The method is applicable to high purity UOP No. 5 and to production stream samples. The following components and group classifications are reported: light ends methyl ethyl ketone (MEK) and methyl ethyl carbinol (MEC) light boiling intermediates monoalkylated UOP No. 5 heavy boiling intermediates UOP No. 5 trialkylated UOP No. 5 and heavies. MEK and MEC co-elute and are reported as a composite. Components that do not elute from the chromatographic system if any under the specified conditions commonly called tars are not determined. The identified components are reported on a tar-free basis. The range of quantitation for any single component is 0.01 to 99.99 mass-%.
